` One object of the invention i`s`-=to provide i f af-bearing structure for and especiallyl applicable to chimney orother ventilators to proj vide for a' free and easy rotation ofa rotatable partfof theventilator.Y f' it s. Another Vob] ect, of' the inventionv is to provide 'a :ballY bearing structure :particularly adapted. for associationfin anystructure involving a ixedand a rotatable partwhere it is'lde'siredthatjthe rotatable part revolve l with aslittlefriction as possibleAV -'Witl1 these and Vother{objects 1n View, the: r invention 'consists in the"` lconstruction .andNr novel combination and a'rrangementY of e parts hereinafter .fullyide'scribed7 illustrated-inthe accompanying drawings and pointed i out in 'the claims hereto appe1 ided,fit'` beingunderstood that various changes/*liny the'formypro-L lportion and minor detailsfof,constructionr.

.My improved bearing is'interposed betweenv `Athe aforesaid'stenizandjstubular member'and 5 by reference 'tothe' accompanying drawing,

This ring a ably v -securedby fastenings 17 to the outer edge of Vvided ywith pockets 19 13o-receive 19 bearingagai-nstthe under face ofthe ring fixed Vtubular stem and .the`

y has VVVa -flange vr7 v which fits"V tubular' formed in the un'dervface` of the complemenf tary ring to/form a raceway-forfbearings,

such as-the bearings `l1'disposed in theapep Y Y y tures 112 of a ball retainerdl interposed Avbetween tlierings 3 and 6,V the 10We1rpngg3 e having. spaced v'apertures 14;' therein at. spaced-x intervals' leading; from the` groove19'- to 'effect dis'chargefof Vwater or any other foreign Vmatl ter which might find its wayinto the Abear-ing.

*A ball yretainer 13is interposed between the l Aannu-lair.-rings "3 and '6 and haslequidistantly spaced-apertures 12 formed Vtherein toire; 1 ceive thebearingbalIs llfwhich arepreferf` g 1 ably of a diameter slightly'greater thanthe` diameter-ofthe aperturesy 14 so as vto support the retainer spaced from y*the lower ring 3 and yet permit ther'balls to rollfinthe raceway V'formed bythe opposing grooves 9 and 10 I l formed inthe rings 3v and 6 respectively;

VTohold the rings 3 and 6 togetherwithrelation to thel retainer 13 and ballsll, any suitable means maybeprovided, `but as shown,

there are a plurality ofY elements, each preferi Y L-slnaped, and each 'havingY one arm416 the annular ringv l6 and having its. other arm.18 extendingunder the lower ringO 3 and pro- 3 whereby to Veffectively connect therrings 3 s and `6 together..y Any suitable numberYV of "these L'.s'hape'd -elementsjmay be employed,k

as willbe understood. v

The retainer 13 maybe T-shaped in cross: section'if desired, andasy shown, providing the retainer13with upper and lower flanges ventilator as is proposed in one application of earingvballs f 2O and'121, respectivelyysoithat'if thebeari ing is ,used yin yconnection with a-ehimney the .present inventionfthe' ian'ges() and 21` will serve' as1 al protection to thevbea'ring against the contents of the'cliimney, and also act, in. anyfevent,V as in'inner support between the'members landg v 'n If desired, a thin collar v22 may be interposed between the outer edges of the annular rings 3 and 6 and the arms 16 of the L-shaped clamping elements so as to exclude water,V snow and ice from the interior of the bearvconnection of the collar 22 and the holding' elements to the upper ring@ is such as not to interfere with a free rotation of the tubular member 2. Y In Fig. 3, the bearing is 'shown -asmodilied slightly, that is, the upper annular ring 6 is provided with a continuousannularflange 23 *to the lower edge of which arms 24 ymay be secured-by suitable fastenings 25. These arms 24 in Fig. v3 will take the place lof the hold-ing devices .previously described, the saine carrying balls- "26 bea-ring` rotatably against the kunder Vface ofthe ring 3. 'This modified structure `in lig. 3 shields and proft'ects lthe interioi` `of the bearing from dirt, Water, snow and ice. Y i

From the foregoing, it will-be'seen thatl provide aV simple, inexpensive, -durablef and eficient ball bearing device, which may be' readily interposedbetween two tubular -meinbers as proposed in the 'accompanying illustration, and that'the bearing embodies such characteristics ythat itis readily applic-able in Yother relations other than that herein specilically noted, and it will be understood that in the accompanying 1claims," ami-not intentionally limiting myself to the -applieaftioiiof the hall 'bearing -to any particular =art,al-

though IV state that it is ellicient in application to ventilators of various `types,particularly that of chimney and 'stack ventilators..

Y Y

5. A'ball bearing comprising a.I pair of rings, bear-ing elements mounted -between the ringsfand a plurality of L-shaped clamping devices, each having one arm rigidly secured :to .one ring,'and having its other arm fcarrying :a bearing element which bears y'slidably against thewother ring, whereby ltofsecure the 4parts rotatively together, and a collar-interposedbetween the rings.

i 6. `A ball bearing comprising a pair of 'annular rings provided with opposing-fannular grooves, bearing elements mounted in said grooves, a retainer interposed between said rings and carrying said bearing ele- V ments, a. plurality of devicesrigidly connected to one of said lrings V and bearing slidably against the other ring, whereby lto secure the parts-together in operative relation, and a collar interposed between the vrings andsaid devices. Y

y 7. A ball-beariiigcomprising a pair of annular rings provided withV opposingA annular grooves, .bearing elements Vmounted insaidV grooves, a plurality of angularlyV shaped ldevices, :elements for-securinglsaid a'n'gularly shaped devices detachably to one-of the rin gs, Y
